I got you! What’s the question
we have the expression
3x+2y
Verify for each ordered pair
so
a) (0,6)
substitute
3(0)+2(6)=12
b) (3,2)
3(3)+2(2)=13
c) (4,1)
3(4)+2(1)=14
d) (5,-2)
3(5)+2(-2)=11
therefore
maximum value for option C
Thanks for your question!
First thing we have to do here is take t to the other side by multiplication:
rx + sx = t
Now, group together, x as the GCF:
x(r+s) = t
Now, divide
x = t/(r+s)
Hope this helps!
Answer:
Step-by-step explanation:
The given equations are:
-9.5x – 2.5y = –4.3 (1)
and 7x + 2.5y = 0.8 (2)
Adding equation (1) and (2) together, we get
-9.5x-2.5y+7x+2.5y=-4.3+0.8
⇒-2.5x=-3.5
⇒x=1.4
Now, substitute the value of x=1.4 in equation (1),
-9.5(1.4)-2.5y=-4.3
⇒-13.3-2.5y=-4.3
⇒-13.3+4.3=2.5y
⇒-9=2.5y
⇒y=-3.6
Thus, the value of x and y are 1.4 and -3.6 respectively.
Answer:
$2475 or $1875
Step-by-step explanation:
Assuming the question meant to say $25 less than the original price, it would be $2475 because $2500-$25= $2475
However, if the question meant to say that Sam bought the iron for 25% less than the original price, it would be $1875 because 2500*0.25= $625
$2500-$625= $1875
